Ignored overclocking settings in bios

post #1 of 7
Thread Starter 
I have been reading from this forum for a while trying to learn how to oc my system. I finally decided to register because I wanted to ask if anyone could shed some light on this problem I'm having.

Until recently, I haven't wanted to take the time to really learn how to do overclocking and would just occasionally use the AI Overclocking to 10% or 15% just playing around.

This weekend I decided to take the plunge. I played around with bumping the FSB a little, etc. with much success. I decided I should upgrade my bios since it was version 0501 (02/07/2007) to the latest version 1002 (02/15/2008) using the EZflash bios utility. The flash went fine and the bios looks right but since then, I cannot get any of the FSB (QDR) changes I make to take effect. I cannot even get the AI Overclocking at 10% to work anymore. After I make the change, save, and reboot, the POST reports 2.4 GHz as if I had not changed anything. When I go back into the bios, the change I made (e.g. AI Overclocking to 10%) is still there so I know I saved it properly but these type of settings just simply get ignored. Funny that my voltage settings (in Over Voltage) and all other bios settings (turning off the splash screen, etc) work normally. It's just apparently anything directly related to the actual oc settings.

I am able to make overclocking changes via Everest (for example) but of course they don't get saved in the BIOS and get lost after reboot. I don't know what else I can do.

Here are the things I've tried:

1. Powering the machine off and unplugging it for several hours.

2. Setting the BIOS back to default and re-entering everything by hand.

3. Removing the battery and doing the CLRTC thing according to the manual. It definitely cleared the BIOS as my date/time, etc. were reset.

I finally decided there must be something wrong with the 1002 BIOS (although I've read plenty of posts of people's success with it) so I decided to try an earlier version. However, none of the BIOS update programs I've tried (ASUS Update, EZflash, awdflash.exe) allow downgrading the BIOS. I wasted several hours trying to find a way to go back to an earlier BIOS with no success.

I would certainly be grateful and rep with passion anyone who could clear this mystery up.

Thank you!

you can try downgrading back to an older bios and see if it is a little better for you. By doing the "CLRTC thing" you've only cleared settings, but are still running the latest bios. Download the bios you had, or maybe the one after it and save it to a flash drive, then load up the bios on boot and do the ezflash from there.

Also, are your settings sticking in the bios? I know you said it loads everything at stock no matter what you do, but when you go in to edit the settings are they where you left them? If not, you may have a bad CMOS battery.

Thanks for the tips h33b.

I'll answer your last question first. Yes, the values are "sticking." They are NOT being set back to default. In other words, when I set AI Overclocking to 10%, POST reports 2.40 GHz instead of the 2.6 (or whatever) yet when I go back into the BIOS it clearly shows that I have it set to 10% oc. Same sort of thing when I go "Manual." FSB related things are clearly being ignored.

On to your first question. Boy, no joke! I wasted about three hours today trying to go back to an earlier BIOS. Using EZflash just as you describe, I get "Cannot downgrade BIOS" and the thing stops right there. awflash.exe using a boot floppy did the exact same thing. The POS ASUS Updater thought the older BIOS was an incorrect architecture and just croaked in confusion. I'm really amazed that apparently once you go to the latest BIOS version with these boards, you have bought the farm. The manual clearly says to use EZflash just as you describe to go back to an earlier version but I'm here to tell you that if you try it, you'll get the error message "Cannot downgrade BIOS."

I sure hope I'm just being stupid and overlooking the obvious but I sure can't see it right now.

Thanks and thank you Sangkim for the kind welcome.

Hmm.... Do you have the CD that came with the motherboard? I know on my last board, P5N-E, and the current one I'm running, you can pop in the cd and boot from it, and do a bios recovery from there. It will load the stock bios and then you can reboot again and try a new one. I'm not sure the exact specs of your board, but the recent Asus boards I have played with all have this feature.

Yessssssssssssssssssssssssss!!

Ok, I tried your suggestion about the bootable support CD. Sure enough, it booted, but it was pretty much garbage. I managed to look through the autoexec.bat file (remember those? ) and figured out basically what the nutty thing was trying to do. I did that and got the "Cannot downgrade the BIOS" message and... oh well.

Finally I did something smart!

I decided to look at the awdflash.exe program with a binary editor just to see if there was any mention of a "force" option or something like that. I had run awdflash /? and got nothing particularly helpful. Sure enough, I spotted a "/f" in the file. I decided to do a google search on "awdflash force" and ran across a guy who talked about downgrading his bios using this command:

awdflash 0901.bin /py /sn /f

I don't know what the other two options do but I sure know what the "/f" is and it WORKED!!

Thank you H33b. You didn't exactly help me but you certainly got me to thinking a little clearer. You were very kind to hang in there with me on this!

So....
bottom line is with respect to the P5N32-EP, BIOS 1002 does not work correctly (at least in my machine) but 0901 does!

I'm back in the overclocking business! Whoo Hoo!
